  • ⚠️ Protect parts when disassembling (they can fall into the sea!)
  • ⚡ Use your drill in screwdriver mode for more torque and control

⛵ IS AN ELECTRIC WINCH WORTH IT?

👉 It depends on your usage.

✔ Occasional use → Not worth spending thousands of euros
✔ DIY solution → ~80% of the benefit for ~1% of the cost

💡 For hoisting sails or lifting loads, this solution is more than enough.
